Rapid denture forming method and rapid denture forming device

Abstract

The invention relates to a rapid denture forming method. The rapid denture forming method comprises the following steps: scanning teeth by using an oral scanner, and forming an initial tooth model; pretreating the initial tooth model; matching the pretreated tooth model with tooth shapes in a tooth shape database, and selecting the tooth shapes with highest matching degree; compiling selected tooth shapes according to an international denture repairing standard, thus obtaining a tooth model which is finally required; carrying out 3D (Three-Dimensional) printing to obtain the denture according to the tooth model which is finally obtained. By adopting the rapid denture forming method disclosed by the invention, the denture forming steps are simple, the forming time is greatly shortened, and the denture forming accuracy is high; the manufacturing cost of the denture is greatly reduced, and promotion and use of the technology are convenient.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a rapid prototyping device for dentures and a rapid denture prototyping method for 3D printing dentures using the device. Background technique [0002] In traditional denture solutions, denture shaping is mainly achieved through two processes of impression taking and manual grinding. The manufacture of dental restorations is used to restore missing teeth in the oral cavity, but the manufacturing process of dental restorations is highly dependent on the technical capabilities of dental laboratory technicians, making it difficult for dental laboratory owners and dentists to produce dental restorations of consistent quality to patients . The difficulty in producing dental restorations of consistent quality is that relatively few dental laboratory technicians have the technical skills or experience. Consequently, there is a high demand for experienced dental laboratory technici...

AI Technical Summary

Problems solved by technology

Therefore, there is a high demand for experienced dental laboratory technicians, but since only a small number of dental laboratory technicians have the necessary experience to fabricate dental restorations, the manufacturing cost of dental restorations is correspondingly increased

[0003] In addition, the existing denture molding production scheme not only has a long processing cycle, but also is difficult to guarantee the processing accuracy. Once the ground teeth do not meet the wearing standards, they have to be returned to the factory for repair, and some are even scrapped directly.

In recent years, with the development of 3D printing technology, many denture solutions rely on 3D printers and 3D scanners to form, but the molded products are the patient's existing tooth model, not the final model that needs to be implanted, resulting in the production of dentures ( Teeth) do not match well with oral teeth
